I would say a dragon salamander butterfly if I had to guess. That means "dragon" scales, three types of colors, and a tail with thick outer liner likes yours. I only guess because I just got my own marble salamander butterfly from AB about a week ago, and I love him to death. :)

Offhand I can't tell you what your fish would be classified under without doing some research but he's beautiful! Welcome to the forum btw.

I got interested in bettas when my mom panicked when her betta got sick. I started research and ended up getting a doubletail who was sick when I got him lol which led me to more research and ultimately here. :D Now I have 8 bettas and would like to breed and show them. ;)

I dont think he is a salamander... arent they supposed to have white on all their fins? Def a HM Butterfly Dragon. Some of the auctions Ive seen them as black devils or flames for the red markings. Just my 2 cents. :) Im not an expert tho! lol
